1971 Satellite/RR/GTX Driveshaft Length HELP!

Hey guys, so I need some help. For those of you who own a 71 roadrunner or satellite, do you know the length of the drive shaft? I have looked at some charts online and found 1971 Dodge Charger driveshaft lengths with my same setup. Just wanted to see if any of you would know.

Here's what I know on my car.

7290
383 CID
8.75 rear with a 727 Automatic Transmission
Swapping out the old drive shaft in my car, long story, but it needs to be done. When I measured it was 51 7/8" the center of each u joint.

Any help would be appreciated.

Looking both models up online, I see both listed as having 115" wheelbases. So, any measurements applicable to the Charger should carry over to the Satellite.

Yep, match transmission and axle model

All 1971 satellite based cars w/383 4 bbl and 727 auto trans have 50.68" Drive shaft lengths

Thank you gents!
